This package contains a kernel patch, which was packaged using dh-kpatches 0.99.27. Here is a generic description the behaviour of such patches. For generic instructions on using those patches, see make-kpkg(8), its --added-patches option, and its PATCH_THE_KERNEL environment variable. - its application will by default only be attempted if the declared kernel version for the patch matches the current kernel's version (unlike patches produced with early versions of this package, which attempted to do things the best they can, possibly producing some confusion). - if this patch depends on other patches, they will be applied in order, and will be removed in reverse order after this one will have been removed. It is not necessary any more to ask for explicit application of these dependencies, but it is not an error to do so. - for each patch you can set the KPATCH_ environment variable to a specific kernel version, if you want to apply a patch that is not declared to work on the current kernel. This can be useful if you want to test a patch on a brand new kernel release that was not published at the time of patch packaging. If the requested version is not found, this patch application will fail.
